[0003] Cable trays are widely used in building interiors, industrial facilities, and other locations to ensure the safety, aesthetics, and reliability of cabling. However, if a cable malfunctions, the cable tray needs to be opened for maintenance. Traditionally, the cable tray cover and the tray are connected by welding and bolts. To facilitate the replacement and maintenance of components later, bolt connections are mostly used. This results in the need for disassembly using specialized equipment after long-term use, increasing the difficulty of maintenance. To address the above problems and defects, there is an urgent need for a cable tray that separates strong and weak current cables. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide a strong and weak current separated cable tray to address the issue that existing cable trays are widely used in buildings, industrial facilities, and other places to ensure the safety, aesthetics, and reliability of wiring. However, if a cable has a problem, the cable tray needs to be opened for maintenance. The traditional method for connecting the top cover of the existing cable tray to the tray is generally welding and bolting. To facilitate the later replacement and maintenance of components, bolting is mostly used. This leads to the need for special equipment to disassemble the device after long-term use, increasing the difficulty of maintenance.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A cable tray for separating strong and weak current cables includes: a tray body and a cover plate; a groove is formed on the top of the inner wall of the tray body, a circular groove is formed on the inner wall of the groove, a spring is fixedly installed on the inner wall of the circular groove, a connecting block is fixedly installed on the end of the spring away from the circular groove, a locking block is fixedly installed on the side of the connecting block away from the spring, a fixing pin is engaged on the outer wall of the locking block, and the top of the fixing pin is fixedly connected to the bottom of the cover plate; a rotating shaft is rotatably connected to the top of the tray body, a connecting rope is fixedly connected to the outer wall of the rotating shaft, the end of the connecting rope away from the rotating shaft is fixedly connected to the connecting block, and a knob is fixedly installed on the top of the rotating shaft.

[0007] Preferably, a partition plate is fixedly installed on the inner wall of the cable tray body, and a positioning plate is fixedly installed on the bottom of the inner wall of the cable tray body.

[0008] Preferably, the top of the cover plate has a fixing hole, and a handle is fixedly fitted onto the inner wall of the fixing hole.

[0009] Preferably, an auxiliary plate is fixedly mounted on the bottom of the cover plate, and the bottom of the auxiliary plate abuts against the top of the positioning plate.

[0010] Preferably, the number of springs, connecting blocks, locking blocks, connecting ropes and fixing pins is two sets, and the two sets of springs, connecting blocks, locking blocks, connecting ropes and fixing pins are symmetrically distributed on both sides of the rotating shaft.

[0012] Compared with the prior art, this utility model has at least the following beneficial effects:

[0013] 1. In the above solution, rotating the knob drives the rotating shaft to rotate. The rotation of the shaft causes the connecting rope to wrap around the outer wall of the shaft, which in turn pulls the connecting block and the locking block to move deeper into the circular groove, causing the locking block to separate from the fixing pin. This allows the cover plate to be removed and the strong and weak cables inside the cable tray to be maintained. Then, the fixing pin at the bottom of the cover plate is inserted into the groove. When the locking block is squeezed by the fixing pin, the locking block and the connecting block move deeper into the circular groove. When the fixing pin is fully inserted into the groove, the spring pushes the connecting block and the locking block to the position of the fixing pin until the locking block and the fixing pin are locked together. This improves the convenience of disassembling and assembling the cover plate, thereby improving the convenience of maintenance of strong and weak cables for workers and increasing the work efficiency of workers.

[0014] 2. In the above scheme, by setting up partition plates and positioning plates, it is beneficial to separate strong and weak cables, prevent the cable installation from being messy, and improve its practicality and aesthetics. Attached Figure Description
